Because Every Drop Counts!

What is CoCoRaHS?

CoCoRaHS, which stands for the Community Collaborative Rain, Hail, and Snow Network, is a unique, non-profit, community-based, high density network of individual and family volunteers of all ages and backgrounds, who take daily measurements of rain, hail and snow in their backyards. By using low-cost measurement tools, stressing training and education, and utilizing an interactive Web-site, our aim is to provide the highest quality data for education and research applications. CoCoRaHS is

now in all fifty states, and starting in Canada.

Where are observers needed?

Observers from any location are welcome! Some locations that we are in desperate need of observers:
- Near the shores of Lake Erie and Lake Ontario (for Lake Effect Snow)
- Along the St. Lawrence River in northern Jefferson County
- Wyoming County
- central Livingston County
- Ontario County
- Genesee County
- Allegany County
- southern Oswego County
- Lewis County
Soon CoCoRaHS will expand to Ontario! http://www.cocorahs.org/Canada.aspx

How do I participate?

You may become a CoCoRaHS volunteer and let us know how much rain, snow or hail has fallen in your back yard by signing up via the website: www.cocorahs.org A personal CoCoRaHS ID will then be issued to you for your location. Online training is available for installing your instruments and measuring the elements. The local NWS office in Buffalo is also available to answer any questions.
All that is needed is enthusiasm about the weather, a quality rain gauge and a snow measuring yard stick. Data is entered via the CoCoRaHS website through your personal CoCoRaHS ID number. Data entry is preferred between 6 AM and 9 AM.
The best part of this program is the National Weather Service in Buffalo, scientists and the public all have the opportunity to view the data, maps and comments through the web on a daily basis.

We would like to have every location represented with CoCoRaHS volunteers. Both scientist and the general public value how much rain or snow falls away from metropolitan areas. Would you like to help fill in the missing gaps?

How does my data benefit others?

The common saying of one town blitzed by a lake effect snow band, while a neighboring community receives just a flurry is true. A network of rain, snow and hail, elements that are easy to measure, can be used by the local National Weather Service and the community. Ground truth data lets forecasters know where the heaviest precipitation fell during an event, and if any areas missed the worst of the storm. In addition Hydrologists, Entomologists, Farmers, Gardeners, Engineers, Media, Students, and many more all use precipitation data within their daily routine.
